AXLE-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 549,882, dated November12, 1895.

Application filed March 20, 1895. Serial No. 542,439. (No model.)

To all whom it may concern:

Be it known that I, JACOB J. BUSENBENZ, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Axle-Lubricators, of which thefollowing is a specification.

My invention relates to that class of axlelubricators having a rollerinterposed between the journal-axle and the lubricant, the axis of eachbeing in line and such roller held or forced against the journal axle byspring power; and the objects of my invention are to supply an axlelubricator to be located within the journal -box and interposed betweenthe journal-axle and the lubricant, wherein the frame in which thelubricantroller is mounted is seated by hanging it from some portion ofthe journal-box, preventing endwise and sidewise movement thereof, andutilizing the hangers of the frame, together with the contact of theroller and j ournal-axle, to prevent vertical movement of such frame;and together with such further and other objects as will be hereinafterexplained and claimed.

I will describe and illustrate my invention when used in connection witha j ournal-box having an upper and lower compartment, the upper beingused for housing the j ournal-axle and the lower being used for storingthe lubricant, a partition dividing the two, the connection orintercourse being had by means of a central slot in such partition, thisbeing a well-known form of j ournal-box used for axles in street-railwaycars. I accomplish these obj ects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 represents a side view of mydevice as it appears when removed from the j ournal-box. Fig. 2represents a sectional longitudinal view of the j ournal-box on the linea: a; of Fig. 3, showing a plan view of my device in position therein;and Fig. 3 represents a sectional vertical view of the journalbox, theupper portion cut away on the line y y of Fig. 2, showing a front endview of my device in position therein.

Similar numerals of reference refer to similar parts throughout theseveral views.

' 1 represents the journal-box; 2, the upper compartment or housing forthe j ournal-axle;

3, the lower compartment or storage depot for the lubricant; 4, thepartition between the compartments; 5 the central slot affording themeans of intercourse or connection be tween the two compartments; 6, thejournalaxle, and 7 the brass bush.

My invention consists in the frame having the horizontalbase 8 and theright-angled vertically-extending uprights 9, from which extend inopposite directions the horizontal bars 10 from the base, and thehorizontal bars 11 from the top of the uprights.

At the extremity of each horizontal bar 11 extends a hanger 12,consisting of a bar extending a short distance vertically and then bentoutwardly at right angles thereto, and to the upper surface of eachhanger I attach a cross bar or rod 13. I construct the frame so that itmay enter or drop through the central slot in the partition and besupported therefrom by the upper or horizontal portion of the hanger,while the extremities of such hangers and the extremities of saidcross-bars or rods abut against the inner surface of the walls of the journal-box and thus prevent endwise or sidewise movement to said frame.

Each horizontal bar 10 and 11 is perforated or pierced in linevertically to accommodate each post 14,-the upper end of such postsbeing constructed to carry a horizontal shaft 15, upon which is suitablymounted a lubricatorroller 16.

Each post 14 is provided with a pin 17, and adjacent to said pin,beneath the same, is a collar or ring 18 surrounding each said post, andsurrounding each said post is a coiled spring 19, the upper end of whichabuts each said collar or ring, and the lower end of which abuts orrests upon the horizontal bars 10, extending from the base 8.

It will be observed that each pin 17 limits the movement of each collaror ring upward upon its post, and the upper end of each coilspring abutsthe collar or ring and its lower end abuts the base 8, and hence whenthe roller is pressed downward such pressure is likewise exerted againstthe springs by means of the pins and collars, and at the same time suchsprings exert a force upward.

When my device is placed-in position in the journal-box, as shown inFig. 3, the journal-axle forces the roller 16 downward sufficiently, sothat through its shaft, posts, pins, and collars it bears upon saidsprings, so as to be held firmly against the journal-axle,and therotation of the latter will cause rotation of said roller. A sufiicientquantity of the lubricant is placed in the lower compartment 3 of thejournal-box, so the lower portion of the roller while revolving willcomein contact therewith, and by this means the lubricant is passed upto and distributed upon the journal-axle.

\Vhile I have shown more or less precise forms, I do not wish to beunderstood as unduly limiting myself thereto, but contemplate changes inform, proportions, and the substitution of equivalent members, as may bedesirable or necessary, so long as the spirit or gist of my invention isadhered to, thin gist consisting, as already described, in a lubricator,of the frame which is suspended from the central slot in the portiondividing the journal-box in the two compartments, such frame constructedand arranged to fit in said j ournal-box and not liable to endwise orsidewise movement, and further consisting of posts provided with across-shaft adapted to carry the roller, such posts passing throughsuitable apertures in the frame whereby the coiled spring respectivelysurrounding each post has a bearing at one end against the base of theframe, and its opposite end against a collar or ring upon suchpost-bearing against a pin therein.

I am aware that it is old in lubricators to arrange the lubricant-rollerso that it is held by spring force against the jOurnaLaXle, and I do notbroadly claim such; nor do I broadly claim the lubricating-rollermounted upon the shaft, the extremities of which are supported by sprin\Vhat I claim as new, and desire to secure by Letters Patent, is

I11 an axle lubricator, havinga roller interposed between the journalaxle and the lubricant, the combination of the cross shaft upon whichthe rolleris mounted, the posts supporting the extremities of saidshaft, the frame provided with horizontal and parallel. cxtending bars,perforated in line to accommodate said posts, a pin secured in eachpost, a collar surroumling' each post beneath each pin, a coiled springsurrounding each post and each spring interposed between a collar and alower horizontal extending bar, a hanger attached to the extremity ofeach upper horizontal extending bar, anda cross-piece attached to anupper member of each hanger, substantially as described.
